WINDOW SASH AND FRAME.

SPECIFICATION forming part of Letters Patent No. 652,273, dated June 26,1900.

Application filed April 16, 1898. Serial No. 677,874. (1 lo model.)

) CLZZ whom it may concern:

Be it known that I, BENJAMIN W. JONES, a citizen of the United States,residing at Dubuque, in the county of Dubuque and State of Iowa, haveinvented certain new and useful Improvements in IVindowSashes andFrames; and I do declare the following to be a full,clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has relation to window sash and frames, and particularly tothat class wherein the sash are adapted to swing upon horizontal pivotsor hinges; and among the objects in view is to provide an improved sashwhich is adapted to be raised and lowered in the usual manner within theframe or which may lie within a stationary window and is also adapted tobe swung upon hori-' zontal pivots or hinges, whereby to enable theglass to be more readily cleaned upon both sides or to be readilyreplaced when broken without necessitating the removal of the sash fromthe frame or to be readily operated from the inside for cleaning orotherpurposes with out the necessity for removing or interfering with thewindow stops or beads, outside or inside blinds, screens, shades, orcurtains.

A further object is to provide such a construction of sash as willeffectually prevent the entrance of air, dust, and moisture at thejoints, and, finally, the object is to simplify,

improve upon, and perfect the general con-- struction of the parts of areversible windowsash, as hereinafter specified; and with the aboveobjects in view the invention consists in the novel construction,arrangement, and combination of parts, as hereinafter fully described,illustrated in the drawings, and pointed out in the appended claim.

In the drawings, Figure 1 is a front view of a window sash and frameconstructed in accordance with this invention. Fig. 2 is a perspectiveView showing the hinged section of the upper sash as swung down intoposition for cleaning. Fig. 3 is a vertical sectional view of the partsas shown in Fig. 2. Fig. 4 is a horizontal sectional view on line a; xof Fig. 1. Fig. 5 is a perspective view of the locking device for thesash. Fig. 6 is a like View of the pivoted thumb lever detached.

Fig. 7 is an endview of the thu mb-lever,showing the bevel.

A indicates the window-frame, whichin its general construction issimilar to the ordinary Window-frame.

B C indicate the window-sash, which are adapted to move verticallywithin ordinary guideways in the frame. Each sash is constructed in twosectionsa complete outer framing adapted to travel within thewindowframe A and a complete inner framing hinged at the lower edge tothe said outer framing and containing the glass. of the sash B and C areindicated by B C, respectively, while the inner hinged sections areindicated by B C respectively. The lower edges of the sections B O arehinged at D to the lower horizontal rails of the two sash, and saidsections are each adapted to be swung upon said hinges into a horizontalposition, as indicated, and their limit of movement is regulated bymeans of links or rods E E, jointed to each other and attached to innerand outer sections of the sash. The said links are adapted to lie withinpockets E formed in the sections B 0 when the said sections are in aclosed or vertical position.

In order to make a close-fitting joint between the inner swingingsections and their outer containing sections, the side portions andupper and lower portions of the outer sections are rabbeted, as at F, toreceive the said inner sections. As will be seen, the rabbets of theupper and lower rails of-the outer sections are of peculiar shape-thatis to say, each upper and lower rail is cut to form two inclined surfaces ,and these surfaces are joined by a vertical surface, thus givingto the rabbet a shape which will prevent or at least retard to a maximumextent the entrance of a driving rain or wind. The sides and up per orlower portions of the inner sections are also rabbeted, as at F, to makea close joint with the outer sections, each of the rabbets F beingsimilar in construction or shape to the rabbets F. Thus I obtain apractically air, dust, and water proof joint between the sections ofeach sash. In order to render the connection between the inner and outersections of each sash as rigid as possible and also prevent unauthorizedmanipulation of The outer sections I the swinging sections from theoutside, I provide each sash with a locking device. (Shown more clearlyin Figs. 5, 6, and 7.) Said looking device consists of a socket portionor keeper G, adapted to be fitted into the side rails of the sections Bnear the upper end, and a thumb latch or lever G, pivoted within ahousing G secured to the side rails of the sections 13 C the point orend G of the lever G being adapted to normally engage within the socketor keeper G when the swinging sections are in vertical position and holdsaid sections rigidly in place. To adapt the end of the lever G toreadily snap into its keeper when the swinging section is being closed,I bevel the engaging end of the lever, as at G, whereby the pressureexerted in closing the swinging section causes the lever to first swingon its pivot and then to snap into the keeper the moment the end Gclears the edge of the socket in the keeper. When it is desired to swingthe hinged section of a sash into an open position for cleaning, or,otherwise, by pressing upwardly upon the opposite end G of each lever G,the end G is drawn Within the housing, thus enabling the swingingsection to be operated. What I claim, and desire to secure by LettersPatent, is

In a window, the combination with the frame, of a sash adapted to movevertically within said frame or lie stationary therein,

said sash comprising an outer sliding section and an inner section thelower rail of which is hinged to the lower rail of the outer section andthe hinged section being adapted to be swung downwardly into asubstantiallyhorizontal position, the side rails of the hinged sectionhaving pockets E linksE E pivoted together and to the side rails of thehinged andouter sections and adapted to unfold and support the hingedsection in its horizontal position and to fold together and lie withinthe pockets E when the hinged section is moved into its closed orvertical posit-ion, the side and upper rails of the outer section beingrabbeted at F and the likerails of the hinged section being rabbeted at13",.

said rails adapted to cooperate as described to make tight joints, and acatch device comprising a keeper in the side rail of the outer section,a housing G on the adjacent rail of the inner section, a lever G pivotedwithin the housing and having a beveled end normally projecting beyondthe housing and adapted to engage the keeper and a projecting portion Gadapted to be operated to cause the beveled end to free the keeper, asdescribed.
